Blow by/Catch can

Just wondering if anyone else is getting blow by?
I took my BOV off the other day and noticed oil coating the inside of the pipes, so I bought a catch can.
Has anyone else had this problem or installed an aftermarket catch can?

Must just be me.

I've installed an aftermarket catch can. Mine is connected to to the pipe out of my rocker cover as well as return back into the air intake pipe. I can't say I've noticed any blow by in my car...

Maybe a seal on your turbo is starting to let go and is weaping thus allowing oil to circulate through??

My car has always had a bit. I've been told by several sources it's normal. Replacing the turbo didn't change anything.

Apparently its pretty common with TX3/323 turbo owners.

I had to fit mine as soon as I fitted the AEM inlet upgrade. I had to put it back to stock in a hurry before it was installed!!!! The original intercooler was in a mess too.

I have only emptied it out once in 10,000 miles.

This was early days and before I sealed off the original little inlet/outlets seen here joined together with the clear hose. I certainly recommend that you use hose of the original Mazda diameter for the best results.
